Well, I don't even make quilt tops! I only Quilt them, so I truly am a "Quilter", but you certainly have more experience than I do! I have tried doing the things you love and it's too advanced for me! I only like the part where I've got something in the sewing machine; you can keep the fabric shopping, the cutting, and the seams! Give me a cone full of thread and a comfy chair! There are some people who enjoy the entire process and are very good at it. Then there are people like us
I think if it's something you're actively doing, you can consider yourself a quilter (or knitter, or baker, or soap-maker, or painter, etc). When I took my 10-year break from quilting, I would mention that I used to quilt. I started up again late last year and now I say, "I quilt!"
